First Implantable Sensor System
for Wireless Restenosis Detection

The Challenge

Intravascular stents are a common treatment for peripheral and coronary artery disease. 540 k procedures in the lower limbs and 1.54 million procedures in the coronaries every year in Western Europe.


These stents share one huge problem:

Restenosis, a gradual re-clogging of the stent over time, occurring in about 5 % – 25 % of all stents within the first 5 years.

Our Solution

The VesselSens diagnostic system is the first implantable sensor system that renders traditional check-ups obsolete by allowing patients to accurately diagnose vessel clogging in real-time. 

Unlike conventional stents which require expensive and highly inaccurate clinical check-ups our patented in-stent sensor technology provides highly accurate wireless diagnosis. 


Follow up examinations are no longer necessary.

Advantages

Compared to State-of-the-Art

  • Measurements in short intervals
  • Early prediction of clogging
  • Easy handling, precise and fast diagnosis

For Physicians

  • Determination of trends and correlation with further vital parameters is possible
  • The restenosis treatment may be induced in an earlier stage
  • Success of therapy is detectable and can be monitored

For Patients

  • Improves life comfort and sense of security
  • Prevention of relapse
  • Reduction of time-consuming check-ups, e.g. physical performance tests, ultrasonic testing

Concept

S1-Grafik_3_homepage

The sensor system is implanted in coronary or peripheral artery during stent implantation or balloon angioplasty. 

The read out device is placed on the body where the stent is implanted.

Our sensor system consists of two sensors which are placed at both ends of the stent.

The read out device is passively and inductively coupled with the sensors in the stent and retrieves PWV (Pulse Wave Velocity) data. 

The PWV is the speed of the pulse pressure wave propagating through the blood vessel.

It transmits these data to a cloud service. 

In the cloud, the VesselSens proprietary restenosis calculation algorithm is stored. Based on the patient specific PWV data, the restenosis degree will be calculated.

The data will be transfered back to the cardiologist or physician within a minute.

It will also be accessable via web interface for clinicians, physicians and patients. For physicians and clinicians there is a possibility to derive trends and detect further important parameters in relation to restenosis.

The result is also shown to the user on the read out device in a traffic light system.
